“…The main difference between our study and that of Zoulia et al [58] is that they were conducted in different climates and were not the same in the urban context. Coupled with rapid urbanization in China, the development of dense park surroundings has altered the role of parks as cooling regulators, resulting in stronger cooling effects in parks during the day than at night [43].…”

“…In the context of urbanization, the impact of buildings on park cooling continues to be tracked. Ruiz et al evaluated the evolution of the cooling effect of the central park and its surrounding built environment in the city of Mendoza, Argentina, over a 10-year period, showing that the densification of the surrounding built environment has increased the thermal inertia of the built environment and the role of parks as thermal regulators; the thermal benefits of the park have changed from being experienced in the evening to the afternoon [43].…”

Urban parks reduce air temperatures within parks and surroundings by exerting the cooling island effect, significant for mitigating the urban microclimate. However, the park cooling effect may be influenced by the surrounding building configuration, and this needs to be studied in more detail, in particular, to explore how to maximize the cooling effect of parks by adjusting the surrounding building configuration. Thus, in this study, the effects of building height, building interval, and building orientation on the cooling effect of a small urban park were investigated using field measurements and ENVI-met numerical simulations. The results demonstrated that (1) building height, building interval, and building orientation all impact the park cooling effect, but their impacts vary. (2) Building height had the strongest effect on the park cooling intensity, and adjusting building height provided the maximum park cooling intensity (1.2 °C). (3) Building orientation had the most effect on the park cooling distance, 100 m downwind of the park. (4) The park cooling effect is best when the surrounding buildings were parallel to the prevailing wind direction, and the park cool island has the greatest intensity and range. This study can guide decision-makers in optimizing building configuration to maximize the park cooling effect.

“…Researchers have undertaken extensive studies on urban microclimates to address the corresponding urban overheating challenges, integrating climate-sensitive design strategies into urban design practices (Jun . Current research indicates that various factors significantly influence the outdoor thermal environment, including urban geometry (Jun Yang et al 2021;Omar M et al 2020;Tania Sharmin et al 2017;Mohammad Taleghani et al 2015;Feng Yang et al 2013), the proportion of vegetation and water bodies (MARÍA ANGÉLICA RUIZ et al 2022;Michael A. Allen et al 2021;Jingcheng Xu et al 2010;Liangmei Huang et al 2008), building and road surface materials (A. Ferrari et al 2020; Julie V. Pham et al 2019;Mohammad Taleghani and Umberto Berardi 2018;Afroditi Synnefa et al 2011), and natural ventilation (Yonghong Liu et al 2020;Yueyang He et al 2018;Yujiao Chen et al 2017;R.

Intensive urban development has resulted in the degradation of the urban thermal environment. Th ere is a growing consensus on the need to enhance urban thermal comfort through well-designed f orms, especially in open spaces like urban canyons. To address this, our study focuses on Xi'an's commercial pedestrian streets, employing K-means clustering analysis to create 32 representative models based on actual scenes, capturing their textural characteristics. Simultaneously, 11 geometri c indicators (2D/3D) were chosen to quantify the canyon's geometric form. We assessed the spatia l and temporal distribution differences in the thermal environment across these models using Envimet simulation. Finally, Spearman correlation analysis was employed to examine the correlation an d significance of the two sets of indicators, culminating in formulating an ideal model. The findin gs reveal that (1) wind conditions are predominantly influenced by the canyon's geometric form, f ollowed by solar radiation and temperature, with the lowest relative humidity change amplitude a mong the assessed thermal parameters. (2) Among the 11 geometric form indicators, 3D indicators correlate more significantly with thermal environment parameters than 2D indicators. Specifically, SO significantly impacts the thermal environment, P holds greater significance than De, and both BSC and BSR are significantly correlated with air temperature and wind speed, with a weaker co rrelation to solar radiation. (3) In the Xi'an region, courtyards oriented north-south demonstrate a more favorable trend in the thermal environment.

“…Platanus hispanica (London Plane trees) and Morus alba (Mulberry trees) are species widely used in the city of Mendoza, both for their size, of 1 st and 2 nd magnitude respectively, and for their shade and ecosystem services of regulation and comfort. In this context, urban trees provide numerous benefits, improving the urban climate, mitigating "heat island" intensity effects in climates with high heliophany; hydrating the atmosphere and reducing summer heat loads with consequent energy savings (22); allowing the retention of suspended particles and noise mitigation by foliage; increasing comfort conditions in public spaces and significantly contributing to urban aesthetics (15). According to dendrochronological analyses carried out in situ (13), the studied specimens show an approximate age of between 90 years (Mulberry trees) and 119 years (London Plane trees), while also showing symptoms of water and thermal stress and some obvious hazard indicators, such as cracks, hollows, and exudates.…”

Urban forests significantly benefit cities and people´s wellbeing. However, under suboptimal growth conditions, they can pose risks. The tree risk and tree hazard assessments in public spaces bring together several protocols for preventing damage to people and property. This article aims to strengthen the database on forest resources at the urban scale and to identify key characteristics of relevant species of street trees in Mendoza-Argentina. In terms of methodology, trees of Platanus hispanica (London Plane tree) and Morus alba (Mulberry tree) were evaluated in situ by indicators related to the probability of failure such as defects, injuries and stress signals. The results show deterioration of part of the urban forest, as well as the greater resilience of P. hispanica when compared to M. alba. We conclude that systematically implementing these assessments will provide guidelines for the sustainable management of urban trees, improving forest infrastructure under sustainable development guidelines. Highlights : Trees growing in cities are conditioned by certain variables compromising their performance. Risk assessment of urban trees considers several measurement protocols, including the rapid visual method. The main problems identified in P. hispanica were cankers with decay, combined with poor branch architecture. M. alba showed more hazardous defects, with an "imminent" likelihood of failure and presence of cankers combined with decay.
